Garnett, who tallied 20 points, 13 rebounds, two blocks and a steal, grabbed a huge board off a Chris Singleton miss in overtime and outletted to Rondo, who found Brandon Bass underneath the basket for an uncontested dunk to all but seal the victory.

Rondo posted his fourth-straight double-double with 18 points and 14 assists, while Pierce totaled 15 points and 10 rebounds for the Celtics, who have beaten the Wizards in the last six meetings.

Martell Webster and Kevin Seraphin scored 16 points apiece for the Wizards, but each had costly turnovers late in the fourth quarter. Rookie Bradley Beal also contributed 16 points in the loss.
